High birth rates are more likely to lead to poverty than to power.

Businesses tend to prefer high birth rates to get cheap labor.

Cheap labor implies reduced purchasing power for most.

We also need food, fresh water, and energy sources.



History should be based on data, not political and economic noise.

To increase your income, get a useful education and have no more than two children.

The real game is to survive on Earth, not in space!

Also: US (USstats.htm, and USstats.xls), UN and OECD data online.

It would be interesting to see what network analysis software does with this type of data:

Try G20: G20.htm and G20.xls!

Data as of 2012:

Such analyses would be much simpler than for the human brain, 20 nodes versus hundreds or thousands.

Network mapping software could also reduce economic and political bias and conflict.

An objective, quantitative analysis of the G20 could be very useful in the

Ukraine – Russia conflict.

Be sure to look at the last sections of the above article!

Maintaining human life on Earth implies maintaining a balanced atmosphere!

Maintaining a balanced atmosphere depends upon countries cooperating!

How do we make the G20 (75% of world GDP) work together?

The costs of not working together could eliminate many species, including humans.


Human population growth is our biggest problem.

I hope these analyses and comments lead to more realistic evaluations of human population growth, energy limitations, and space exploration so future generations can enjoy a productive life on Earth.

James M. Pickett, September 25, 2007.


Definition of Overpopulation:

I define overpopulation to mean having a less than desirable GDP/capita and being willing to reduce the birth rate to help increase the GDP/capita even if the population is stable.


This means that a country may need to decrease its population to raise its GDP/capita.  If a country is trying to expand into another country (by force or by migration) or is so unstable that it is endangering others, then countries may act to defend themselves.  Stabilizing overpopulated countries may require pressure from more developed countries.  For example, foreign aid might be granted only if the birth rate is significantly reduced.  Access to welfare, including food, is not a right, it is a privilege earned by responsible reproduction and hard work.

          18. A climate proposal: Rich countries (high GDP/capita and low birth rates) agree to develop and help finance technologies to begin reducing global warming by 2050. Rich and poor countries (low GDP/capita and high birth rates) agree to reduce birth rates to two per female or less by 2050.  If successful, we would stop global warming and be approaching a stable human population by 2050. Middle income, low birth rate countries (e.g. China and Russia) could aid these important negotiations. Such projects should be funded as a percent of GDP: Climate.htm and Climate.xls
